Slide Rail Connecting Mechanism for Drawer Alignment Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail systems face challenges in aligning drawers with slide rails due to minor mounting errors, leading to difficulties in installation and increased production costs from complex adjustment mechanisms.
Innovation Solution
A slide rail system with a rear connecting device featuring a locking element and movable element allows for transverse adjustment of the drawer's mounting position, and a front connecting device with an adjusting element enables alignment of the drawer relative to the slide rail, simplifying the adjustment process and reducing component complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex adjustment mechanism with multiple components is used to eliminate mounting errors, then the alignment precision is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent combines the adjustment function and locking function into a single integrated connecting device. The connecting device includes a connecting body with a connecting部 that can be adjusted transversely and a locking element that secures the adjusted position, eliminating the need for separate adjustment mechanisms and reducing overall component complexity while maintaining alignment precision
Solution Approach 2:
The connecting device serves multiple functions: it connects the drawer to the slide rail, allows transverse adjustment to eliminate mounting errors, and locks the adjusted position. This multi-functional design replaces what would traditionally require multiple separate components, reducing device complexity while improving manufacturing precision
2Ease of manufacture
If a simple connecting device is used, then the production cost is reduced, but the ability to adjust for mounting errors is lost
Solution Approach 1:
The connecting device incorporates a movable connecting部 that can be adjusted transversely relative to the locking element. This dynamic capability allows the device to adapt to mounting errors while maintaining a simple overall structure. The connecting部 can move to different positions and be locked, providing adjustability without requiring complex mechanisms
Solution Approach 2:
The connecting device enables easy adjustment and locking by the installer without requiring specialized tools or complex procedures. The transverse adjustment capability allows the installer to self-correct mounting errors, and the locking element secures the position automatically, making the device both adaptable and easy to manufacture
3Manufacturing precision
If multiple separate components are used for connection and adjustment, then the adjustment precision is improved, but the ease of installation is reduced
Solution Approach 1:
The patent merges the connection, adjustment, and locking functions into a single integrated connecting device. This reduces the number of components that need to be handled and assembled during installation, making the process easier while maintaining the ability to achieve precise mounting through transverse adjustment of the connecting部
4Reliability
If a complex multi-component system is used, then the reliability of connection is improved, but the productivity of assembly is reduced
Solution Approach 1:
The connecting device is segmented into functional modules: a connecting body with connecting部 for attachment, a locking element for securing, and a movable mechanism for transverse adjustment. This segmentation allows each component to be simple and easy to manufacture, while the coordinated operation of these modules ensures reliable connection and fast assembly, improving both reliability and productivity

AI summary
A slide rail assembly includes first and second rails. The second rail, slidable relative to the first rail, has a rear portion. A connecting device includes a main body containing a supporting portion and a transverse portion substantially perpendicularly connected to the supporting portion, a locking element pivotally connected to the supporting portion, and a movable element. When the locking element is rotated to a first position, a contact portion of a locking rod is pressed against the moveable element; once the locking element is rotated from the first position to a second position, the contact portion of the locking rod is no more pressed against the moveable element, thus allowing the movable element to be displaced relative to the main body.
